The one on the left is Carbide Black, it has a texture that feels a lot like truck bed liner but it's less coarse.
The center option is Silver Vein, it's silver and black and has a very nice texture to it.
The final option on the right is Copper Vein. It's difficult to tell but the box has the same texture as the Silver Vein but it has a deep copper tone to it. Though in the the images it looks like the Carbide Box, it is very different in both color and texture.
Please refer to the Macro images in the comments below for a better indication of what I mean.
